To all whom it may concern:

Be it known that I, Crmnnns V. Foorn, a citizen of the United States,residing at Nephi city, in the county of J uab and otate of Utah, haveinvented certain new and useful Improvements in Electric SignalingDevices for Moving-Picture Rewinding Mechanisms, of which the followingis a speci fication.

This invention relates to film rewinding or reversing mechanism formoving picture machines, and particularly to signals therefor.

One object of the invention is to socon struct a mechanism of thischaracter that the film may be rewound r reversed at the same time thatanother film is being exhib-' ited, and notice of the completionofrcwinding given to the operator.

Other objects and advantages will be apparent from-the followingdescription when taken in connection with'the accompanying drawings. y

In the drawings: Figure 1 is a side elevation showing the apparatus asused in connection with the usual motion picture machine. Fig. 2 is afront elevation of the rewinding mechanism. Fig. 3 is a verticalsectional view on the line 33 of Fig. 2,

and Fig. 4 is a vertical sectional view on the line 1-4 of Fig. 2.

Referring to the drawings, the numeral 1 designates 'a supporting tablehaving mounted thereonthe usual apparatus for exhibiting motion pictureswhich, includes upper and lower film magazines 2 and 3, and a takeupshaft 4. Leading from a pulley (not shown) on the shaft 4 is a belt 7,said belt being trained around a pulley 8 mounted on the shaft 11 whichis mounted in a casing 10. One-end of this shaft carries a reel 9 onwhich the film is rewound. This shaft is suitably supported in bearings12 and 25 carried by the casing 10. Suitably mounted in thecasing 10andparallel with the shaft 11 is a stub shaft 22, said stub shaft carryingthe reel 23 on which is wound the film-that has been previouslyexhibited and which is to be wound on the reel 9.

A guide-way 33 is formed in the top of the casing 10 directly over theshaft 11, and adapted to move vertically through this guide-way is a rod34. To the lower end of this rod is secured a yoke 35 having journaledin its ends a shaft 36, and rotatably mounted on this shaft is a rubberroller 37,

this roller bearing on the film of the reel 9, as the film 1S. beingWound thereon. Carried upon a portion of the yoke 35 is a preys-c tion38, said projection being .for the our- 'cator or circuit closure isadapted to travel vertically when the film is being rewound or reverseduntil the said yolt'e 35 reaches such position that the projection38'will move the contact 21 into engagement with the'contact 2G tocomplete an electric circuit, in whichis included a suitable filflffl'l.Ar ranged intermediate the reels 9 and 23 are guide rollers 40 and 41,said rollers guiding the film from one'reel to the other.

In operation, the film having been wound by the exhibiting machine, thisreel or liini is placed in the casing 10 upon the shaft 522. The end ofthe film is then passed over the roller 41 and under the roller 4G andcured to the hub of the reel 9 by a sui'tal clip. The proper clutch (notshown; he

thrown into locking position, and upon t operation of the usualprojectin a nism, motion is imparted from the pulley, carried by thetakeup shaft tl'irou i the belt, which in turns rotates the sin iii,thereby rewinding or reversing the same time that another film is scihibited. As the film winds upon t-h 38 forces the oontdct 21 into engag,with the contact- 20. The circuit wili ti be closed and the signalsounded so that operator will know that the film reel has beentransferred to the reel 9, whereupon he disengages the mechanism fromthe exhibiting machine.

What is claimed is:
